Answer:
The answer might be D
Explanation:
The answer could be D because birds with larger beaks should be capable of eating soft shell seeds, as well as hard shell seeds. So natural selection would not occur because the finches with large beaks would not die as a result of not eating soft shell seeds. The finches with large beaks should be able to reproduce offspring with the same trait. And so should the finches with small beaks.

Explanation:
it is broken down to produce energy
Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.
The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.
Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.
Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.
Crossing over is important as it allows for variation in a species. Without crossing over or any other methods of providing genetic variation it would mean everyone would look the exact same.
<span>C) The age of a fossil can be determined by examining the rock strata in which the fossil is found.
[ Age can be determine, that's why Scientists can predict an event on Geographical scale, so evolution could be studied ]
